I am having problems with my bluetooth. I can only use controllers when they are plugged in via usb and my headset won't connect. I have tried resetting the controllers, resetting the console, restoring default settings, letting the controllers die and reconnect. I am wondering how hard it would be to change the bluetooth chip in the console. Any info would help. Thanks.

Did it use to work (blu-tooth)? If not you might have one of the rare, incompatible ones, unless it's official or something. Is your console under a year old because i would have sony fix those problems if so.

Some people have these problems since the update, the controller thing specifically, so you might want to wait for then next update to see if they fix it. Sony knows of the issues with the 3.0 update so a fix should be coming soon.

You won't be replacing any chips, unless you are an expert at desoldering surface mount parts, and putting a new one on, resoldering it. If it doesn't work, then it doesn't work, there is no way YOU are fixing it, unless it is a plug-in board or part.

The problem, why WiFi and BT fail? In the USA, it is against the law (stupid as hell), for both a BT and WiFi transceiver to be broadcasting and receiving at the SAME TIME. So, they multiplex both signals, turning them ON and OFF alternating each other, many MANY times a second to produce what seems to be a continual signal... Stupidest thing I ever heard.. Damn FCC can't tell if they're talking or farting half the time, those idiots...
